In order to reduce the unlocking difficulty of the first unlocking mechanism 5 and reduce the rotation angle of the rotating seat during unlocking, the directions of the seat stump 1 in the left side position state and the right side position state can be set to be unlocking directions, that is, the seat stump and the frame are converted from the locking state to the unlocking state only by 90 degrees.

At this time, the locking clamping blocks 33 and the locking clamping grooves 34 of the second locking assembly are arranged at two positions, for example, the locking clamping grooves 34 are respectively arranged at the left side and the right side of the assembling seat 21, and the locking clamping blocks 33 are also arranged at the left side and the right side of the rotating seat 11 (based on the direction when the seat 1 is in the front riding state); or the locking clamping grooves 34 are arranged on the front side and the rear side of the assembly seat 21, and the locking clamping blocks 33 are also arranged on the front side and the rear side of the rotating seat 11. It will be appreciated that the locking latch 33 can be completely disengaged from the locking slot 34 when the seat 1 is in either the left or right position.

Correspondingly, a plurality of guide grooves 31a on the locking cover 31 are arranged and are arranged in a central symmetry manner, and guide bosses on the locking table 32 are in one-to-one correspondence with the guide grooves 31a, so that when the locking cover 31 rotates on the locking table 32 for one circle, two unlocking opportunities are also provided, namely, when the locking cover 31 rotates for 180 degrees, the projection of the guide grooves 31a to the direction of the locking table 32 coincides with the position of the guide convex blocks 32a once. In this embodiment, four guide grooves 31a are disposed on the locking cover 31 in a surrounding manner, the four guide grooves 31a are respectively located at two ends of two mutually perpendicular diameters of the locking cover 31, the lengths of the guide grooves 31a corresponding to the same diameter are the same, the lengths of the two adjacent guide grooves 31a are different, and four guide protrusions 32a corresponding to the guide grooves 31a one to one are disposed on the locking table 32.

In order to make the two sets of unlocking orientations of the first locking assembly correspond to the front riding position, the rear riding position, the left side position and the right side position respectively, the included angle between the two locking grooves 21c on the assembly seat 21 is 90 degrees, when the lock tongue 41 is inserted into one of the locking grooves 21c, the unlocking orientation of the first locking assembly is the orientation of the rotating seat 11 when the seat stump 1 is in the front riding position and the rear riding position respectively, when the lock tongue 41 is inserted into the other locking groove 21c, the unlocking orientation of the first locking assembly is switched, and at the moment, the unlocking orientations are the orientations of the rotating seat 11 when the seat stump 1 is in the left side position and the right side position respectively.

In practical use, we can confirm the unlocking orientation of the first locking assembly according to the orientation of the locking assembly, in order to unify the judgment standard of each baby carrier, the four guide grooves 31a on the locking cover 31 can be aligned with the front, back, left and right directions of the seat 1 when the locking cover 31 is installed, the four guide protrusions 32a on the locking platform 32 are aligned with the front, back, left and right directions of the guide seat when the first locking assembly corresponds to each unlocking orientation, and the locking tongue 41 and one of the guide protrusions 32a are in the same orientation, so that the locking assembly perpendicular to the locking tongue 41 is also directed to the front and back directions or the left and right directions of the seat 1, thereby obviously seeing the orientation of the locking assembly.
